How to convert teaspoons (us) to gallons (us)
1 teaspoon (us) is equal to 0.00130208333471 gallon (us):
1 tsp = (0.00492892159375 L ÷ 3.78541178 L) gal = 0.00130208333471 gal
Each teaspoon (us) is defined as 0.00492892159375 L and each gallon (us) as 3.78541178 L, so one tsp equals 0.00492892159375 ÷ 3.78541178 gal = 0.00130208333471 gal.
Let V(tsp) be the numeric value of the same volume measured in Teaspoon (US) (tsp), and V(gal) the value in Gallon (US) (gal). Then:
V(gal) = V(tsp) × (0.00492892159375 / 3.78541178)
Equivalently, divide by how many tsp fit into one gal (liters per gal divided by liters per tsp):
V(gal) = V(tsp) ÷ 767.99999918846345
Or: gallon (us) = teaspoon (us) ÷ 767.99999918846345
Examples
Example #1: Convert 20 tsp to gallon (us)
20 tsp = 20 tsp × (0.00492892159375/3.78541178) gal = 0.0260416667 gal
20 tsp = 20 tsp ÷ 767.99999918846345 = 0.0260416667 gal
Example #2: Convert 50 tsp to gallon (us)
50 tsp = 50 tsp × (0.00492892159375/3.78541178) gal = 0.0651041667 gal
50 tsp = 50 tsp ÷ 767.99999918846345 = 0.0651041667 gal
